MOP HOLDER AND W BIN GER.

Application filed December'23, 1920, Serial No.432,659.

To all whom it may concern:

Be it known that I, EDWARD MONA- MARA, a citizen of the United States of America,and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvementsin Mop Holders and Wringers, of which the following is a specification.

This invention relates to that type of household mop holders and wringers in which the wringingmeans is combined with the-holding and manipulating means, and

has for its objects:

To provide a structural formation and association of parts in the mop carrying frame wherebya strong and durable journal connection between the frame and the mop, carrying drum is provided, and which in addition provides an effective attachment of the mop handle or stick to said frame.

To provide a structural formation imparting resiliency to the mop carrying drum and permitting a peripheral contraction ofthe same under excessivestress in a mop wringing operation to attain an effective squeezing action on the mop material.

To provide means for operatively connecting the operating lever to the drum in a substantial yet readily disconnectible manner, all'as .will hereinafter more fully appear.

In the accompanying drawing =Fig. 1, is a front elevation of a mop frame and wringeraembodying the preferred construction of the present Invention. Fig. 2, is a detail sectional'end view of the. same, with the mop material removed.

3, is an end elevation, with parts broken awayfland with the mop material in itsordinary depending condition.

Fig. 4;, is a companion viewto Fig. 3, with the mop. material in a wringing position on the carrying drum.

Fig. i 5, is another companion view, illustrating the mop material in a subsequent and partly released position in relation to I the "drum, for use in mopping confined places. l Fig. 6, is adetail cross-section of'the drum. I

7, is a detail plan view of an end portion of the drum.

Fig. 8, is a front elevation of amodification embodying the applicationof the pres- -ent.i mprovernent to a solid drum or roller.

modification illustrating a modified construction of the peripherally contractile drum. s

Fig. 11, is an end elevation of the same. Like reference numerals, indicate like parts in the several views.

Referring to the drawings, 1 designates the holding frame of the usual yoke shape and comprising a main longitudinal. rail 2, a central socket member 3. adapted to'receiive the mop handle or stick 4, and, endlring'stfin parallel relation. The rings 5 have afdiameter corresponding to that of the mopv drum or roller and are, adapted to form bearings for the. respective ends of said drum or roller.

In the construction illustrated in'Figs. 1 and 3 the framefl is formed from a'single bar or rod of metal of the required length,

which is folded at'the mid-length with the spective outer ends of the bar 2 to :provide journal bearings for the hereinafter describedrevoluble mop drum, and 2' designate brace portions of the bar orrodextending diagonally towards the mop handle at to which they are attached to. aflo'rd additional strength to the frame 1.

The described construction of the holdingsocket 3 affords anheifective. attachment for the end of the handle A: suohattachment being attained by turning the tapering end of the handle in the cavity of the, spiral members to effect an expansion of the same,

and an effective, holding engagemento'fthe parts. I, I,

I6 designates the cylindrical mop drum or roller, which in the preferred form shown in'Figs. 1 to 6 inclusive, isformedfroman orificecl sheet of metal :bent into a cylindrical shell with the adjacent peripheral edges thereof in disconnected relation i to provide an open space or gap, -so-that nd e s imposed utlier? of the drum during a mop wringing operation the cylinder will be capable of resilient contraction and in its tendency to return to its normal size will exert a very effective squeezing action on the mop material.

7 designate out turned flanges or lips on the respective ends of the drum 6 for preventing endwise movement of the drum in the journal rings 5 of the frame 1, while 8 designate inturned flanges or lips at the ends of the drum to provide bearings or abutments for the operating handle hereinafter described.

9 designates a longitudinal recess or depression formed in the periphery of the drum 6, and either of the concave form shown in Figs. 2, 3, 4, and 5, or the flat form shown in Fig. 9, as deemed most desirable. The purpose of the recess 9 is to receive the fold of the mop material 10 at the point of operative connection to the drum, so that said fold may be in proper relation to the axis of the drum and attain an even rolling of the mop material around the drum in a mop wringing operation.

The means for effecting a manual rotation is in many respects the same as shown and claimed in my companion application for Letters Patent Serial No. 432,658, and

comprises a member havinga formation as follows 11 designates a rod, which When in posi- .tion, has parallel relation to the peripheral recess 9 of the drum 6, and adapted to receive the attaching fold of the mop material 10 to hold the same in proper operative connection with the drum. I

.12 designate angularly' disposed extensions at the respective ends of the aforesaid rod 11 and" adapted to pass through slots and orifices in the circular wall of'the drum 6. with the end of the extension 12 to the right in the drawing bent outwardly and passing inside the drum in operative position between the inturned lips 8 of the drum above described, forconnection to an operating lever member as follows I 13 designates an operating lever extending from. the outwardly bent extension of the aforesaid portion 12 to the right, and provided at its free end with an operating handle 13 for convenient manual rotation. Said lever is also provided with a prong 142 for engagement with the resilient latch piece 15 theretofore described, so that with said parts in engagement the lever 13 is held against turning movement.

With the described construction an outward pull on the lever 13 will cause said holding member, to assume the position shown in dotted lines in Fig. 1, and permit of a ready removal and replacement of mop material 10 from and onto the rod portion 11 aforesaid.

The modified arrangement of parts illustrated in Figs. 8 and. 9 is similar in some features to that set forth in my companion application Serial No. 432,658, with the angular extensions 1 of the operating means having operative engagement in diametric channels formed in the respective ends of the drum or roller 6.

In the modified arrangement of parts lllustrated in Figs. 10 and 11, the rod 11 of the drum operating member aforesaid has engagement in eyes 16 on one of the longitudina-lly curled edges of the wall of the drum 6, while the other longitudinally curled edge of said wall is provided with eyes 16 for a separate rod or section 11' adapted to carry the mop material 10 as shown.

In the present mop structure the wringing or squeezing of the mop material 10 is effected by a revolution of the drum 6 to cause a winding of the mop material upon the perimeter of the drum and carry the mop material tl'irough the restricted throat or space between the perimeter of the drum and the longitudinal bar or red portion 2 of the holdingframe 1 to attain an effective compression or squeezing action upon the mop material. With a movement of the drum in a reverse direction the aforesaid portion 2 acts to retard the mop material so that the squeezed portion of the same will bank up and become loosened as illustrated in Fig. 5. ready for a mopping operation in confined places- Having thus fullv described my saidinvention What I claim as new and desire to secure by Letters Patent is 1. In a mop holder and wringcr, the combination of a revoluble drum, a frame hav ing bearing rings at its ends of an internal diameter equal to that of the drum adapted to encircle and provide peripheral bearings for the ends of the drum. means for preventing longitudinal movement of the drum in the bearing rings. means for attaching the mop material to the drum, and means for imparting rotation to the drum.

2. In a mop holder and wrmger, the combination of a revoluble drum. a frame hav ingbearing rings at its ends of an internal diameter equal to that of the drum adapted to encircle and provide peripheral bearings for the ends of the drum, said drum having out turned stop flanges at its ends for abutment against the bearing rings to prevent independent movement between the parts, means for attaching the mop material to the drum; and means for imparting'rotation to the drum.

4. In a mop holder and wringer, the combination of a revoluble drum, a frame formed of rod metal shaped to provide a longitudinally extending rail having bearing rings at its respective ends and a central spiral tapering socket, the said bearing rings being formed to encircle and provide peripheral bearings for the ends of the drum, means for attaching the mop material to the drum, and means for imparting rotation to the drum.

5. In a mop holder and wringer, the combination ofa revoluble drum, a frame formed of rod metal shaped to provide a 1011- gitudinally extending rail having diagonal side braces, bearing rings at its respective ends and a central spiral tapering socket,

: the said bearing rings being formed tov encircle and provide peripheral bearings for the ends of the drum, means for attaching the mop material to the drum, and means for imparting rotation to thedrum.

6. In a mop holder and wringer, the combination of a revoluble drum, a frame having bearing rings at its ends adapted to encircle and provide peripheral bearings for the ends of the drum, a longitudinal rod adapted to' support the mop material and having angular extensions at its ends for engagement with the circular shell of the drum, and an operating lever for the drum attached to one of said extensions.

7. In a mopholder and wringer, the com-' bin-ation of a revoluble drum, a frame having bearing rings at its ends adapted to encircle and provide peripheral bearings; for the ends of the drum, a longitudinal rod adapted to support the mop material and having angular extensions at its ends for engagement with the circular shell of the drum, an operating lever attached to one of said extensions, and a latch member mounted on the frame and adapted to engage said lever.
